The Government's official website features a link to the Cheshire Resilance Forum which says the following about an Emergency grab bag: "If you are asked to leave your home by the emergency services, take your complete Household Emergency Life-Saving Plan plus your Emergency Grab Bag and leave as quickly as possible.

"An emergency could happen at any time. Making an emergency supply kit, an Emergency Grab Bag is one simple thing you can do to make sure you and your family are ready. An Emergency Grab Bag is a useful bag packed with essentials in case you have to evacuate.

Keep an Emergency Grab Bag in your car. This is extremely important during cold weather.

It should include the following:

Suitable winter clothes and a blanket or a sleeping bag

Mobile phone, torch, radio and extra batteries

Shovel and windscreen scraper

Tow chain and rope

Jump leads

The UK-based 30days30ways website says: "When people talk about emergencies you may think of recent tragic events such as the attacks on London and Manchester, recent UK storms and flooding, the Nepal earthquake, the Indonesian tsunami or other global disasters.

"What if we told you that being prepared is not just for those head-line grabbing incidents? Power cuts, water main bursts, gas leaks, fires, transport strikes, road closures etc. can happen any day.

"Taking proactive steps to be better prepared will help you not only with everyday emergencies but also with far less likely incidents.
